I've been running WinDirStat to clean up my harddrive. One folder it reports as consisting of 2GB files, and it's also showing these files, but using explorer or the command line, there is nothing there.
I've run CHKDSK /F /V /R 2 times, but it does not report any errors. What's going on here?
I've gathered some info in a screenshot (a bit german, but you should get the idea):

Not sure one can actually read this, so here goes:
- A Folder
C:\Program Files (x86)\Alpenverein\Alpenvereinskarten Digital 2010is shown in WinDirStat containing 2GB worth of map files, but this folder does not show up in cmd or Explorer. - Opening the properties of a map file, the Common tab shows 50MB size while the details tab shows 0byte size !??
- WinDirStat can open a cmd prompt to this path, although it apparently isn't there!?? (
dir .yields "File or Directory not found") Explorer doesn't show anything (obviously I've checked it to display hidden and system files.)
What's going on here? What can I do?
